Max Anderson: Cycling Instructor

“It’s never too late to become what you might have been.”  –George Eliot

Basically I feel like that person who woke up one day and said “I’m going to make a positive, challenging life change for myself and make it work.”  I was at a point where I was feeling very directionless and began noticing years of fatigue catching up with me, so I decided that I needed a fresh start and to work towards something different from anything I had pursued in most of my life.  I started exercising every day I possibly could and began eating healthier with the goal in mind of one day being a personal trainer/fitness instructor.  “Being a fitness instructor means not only getting to change myself for the better, but to positively affect other peoples’ lives on a personal level as well.”

Max loves spinning to different genres of rock music and creating interesting themes that you will remember.

Vona Kuczynska: Cycling Instructor

“If life gives you lemons, make lemonade… Then find someone whose life has given them tequila, and have a party!”

Growing up, I practiced martial arts and participated in track and field, rowing, and cycling. I enjoyed organized sports because I’m social, enjoy pushing myself, and competing. These days, I mostly compete against calories from beer, French fries, and chocolate. They are a tough adversary!

I started spinning to combat the enemy, listen to good tunes while working out, and meet interesting people – all at the same time! As a wildlife biologist, I spend most of the summer in the woods, climbing trees, catching and tracking birds and bats, often up and down mountains while carrying a 40-pound backpack. It helps to stay in shape the rest of the year and keep my legs and core strong so that come summertime, my only worries are mosquitoes and the heat!

In my spare time, I enjoy all the typical granola activities: hiking with my dogs, riding my bike, backpacking, camping, canoe/kayaking, climbing, microbreweries, and traveling to remote natural places.

Favorite spin music: Anything upbeat with a fast tempo that I can wiggle around to such as Bloodhound Gang– The Bad Touch or Outkast– Hey Ya!
